Google took over YouTube 5 years ago, and in celebration of the anniversary recently invited K-pop artists to Google headquarter and held large scale concert at Shoreline Amphitheatre.

The fever of the audiences at the K-pop concert was great as its first concert in Silicon Valley. 22,000 seats were filled fully while another 3,000 Google employees and clients enjoyed the amazing show.

Alex Carlos, head of YouTube entertainment, came up to the stage and commented before the concert "K-pop became a PHENOMENON. We were very surprised that all 22,000 tickets were sold out within an hour."

According to one Korean media, Alex also stated “This event became an important opportunity to confirm the possibility of globalization of media as to see one small East Asia country cultural contents to spread out through the world.”
